从零搭建SpringCloudAlibaba开发框架-001-认证中心

1. 在gitee上新建代码仓库，一开始建的会是私有的，建完之后再改成公开的

 2.迁出项目

 3. 创建父项目

4.添加父项目依赖

 4.创建Module

5. 认证模块依赖

以上内容参考了：mingyue: 🎉 基于 Spring Boot、Spring Cloud & Alibaba 的分布式微服务架构基础服务中心

报错及解决：

错误信息：Web application could not be started as there was no org.springframework.boot.web.servlet.server.ServletWebServerFactory bean defined in the context.

解决办法：

在main方法上添加@SpringBootApplication
